Summary:

• **What Happened**: Disney and Paramount Pictures sent legal letters to a Chinese company called ByteDance, telling them to stop using their movies and characters without permission. ByteDance was using artificial intelligence (AI) to create videos that looked like they came from Disney and Paramount movies.

• **Why It Matters**: When companies create movies and characters, they own those ideas. Using them without asking is against the law. This case shows how AI technology is being used in ways that can break copyright rules, and big companies are fighting back to protect their work.
